' Application filed February 3, 1927. Serial No. 165,575.

This invention relates to improvements in poles or posts andparticularly to an assem-' bly or" skeleton or open-frame posts in whichthe spread of the post will provide unusual strength and stabilityrelatively to the amount of material used. Further improvements relateto the details of connecting the web-members of the post to the verticalmain or supporting members.

The annexed drawing and the following description set forth in detailcertain means embodying my invention, such means constituting, however,but one of the various forms by which the principle of the invention maybe illustrated.

In said annexed drawing:

Figure 1 is a perspective view of the im proved post;

Figure 2 is a plan view;

Figure 3c is an enlarged fragmentary perspective, showing in detail themethod herein described for connecting the web-members to the mainsupporting members; and

Figure 4 is a plan view of the elements as shown in Figure 3.

Referring to the annexed drawing in which the same parts are indicatedby the same respective ordinals in the several views, I indicate by theordinal l a plurality of vertical main supporting members, the same asherein shown being three rods assembled in the completed post to formthe corners of an equilateral triangle as plainly shown in Figure 2.

These main members 1 are cut to desired length and clamped in suitableassembling mechanism at spaced distances providing the desired spreadand are then rigidly eonnected together by tie-bars 5, the latterbeingof a length to reach from one main mem her 1 to an adjacent member 1 ina sloping position, substantially as shown in the accompanying drawing,the adjacent tie-bars 5 being secured to the members 1 with their endsin close proximity, so that the plurality of tie-bars 5 form in eliect acontinuous spiral web member 2. In the accompanying drawing, forpurposes of illustration, I have shown the web member 2 as encirclingthe main members 1. and exteriorly crossing or bounding the latter.Horizontally arranged top and bottom strengthening web members 3 and 4are wrapped about the ends of the members 1 and welded thereto asindicated by the ordinal 11.

In order to secure a strong and rigid connection between the tie-bars 5forming the continuous spiral web member 2 and the main, members 1 atthe points where the spiral web member crosses the member 1, Ilongitudinally split the tie-bars 5t0. form adjacent pairs of barsections 5 5 5 and 5", preferably of equal size, illustrated by theenlarged view of Figure 3 wherein one crossing point of the web bar 2has been developed to show this detail construction and method ofuniting the tie-bars to the main supports, the two pairs of splitsections, 5 -5 and 5 5*, being bent in opposite directions about theadjacent member 1 and rigidly secured thereto, preferably by welding, asindicated by the ordinal 10. The result of this rigid connecting of theindividual tie-bars to the members 1 is to form what is in effect acontinuous spiral member 2 transversely cut in the plane 6 at eachcrossing point upon the main members 1 and rigidly united with the mainmembers 1 at these crossing points, producing a post of comparativelygreat effective spread which furnishes unusual strength and stabilityfor the amount of material used.

WVhat I claim is: 1.' A post comprising spaced vertical supporting bars,and a spiral web bar bounding said vertical bars from end to end, saidweb bar being divided into individual tie-bars at its crossing pointsupon the respective vertical bars and having the adjacent tiebar endslongitudinally split and the respective split sections bent about therespective adjacent vertical bars in opposite directions and rigidlysecured thereto, thus forming in effect a continuous web-bar.

2. A post comprising spaced vertical supporting bars, and a. spiral webbar bounding said vertical bars from end to end, said web bar beingdivided into individual tie-bars at its crossing points upon therespective vertical bars and having the adjacent tie-bar endslongitudinally centrally split and the respective split Sections wrappedabout the respective adjacent vertical bars in opposite directions andwelded thereto, thus forming in effect a continuous web bar.

3. A post comprising spaced vertical supporting bars, a spiral web barbounding said vertical bars from end to end, said web bar being dividedinto individual tie bars at its crossing points upon the respectivevertical bars and having the adjacent tie barends longitudinallysplitaind the iespective split sections bent about the respectiveadjacent vertical bars in opposite directions and rigidly securedthereto, thus forming in ef feet a continuous Web bar, and upper andlower horizontal Web bars bounding the ends of said vertical bars.

4. A post comprisiru; spaced. vertical supporting bars, a spiral Web barencircling said vertical bars from end. to end, said web be! beingdivided into tie hers in the planes where it cx-teriorliy crosses therespective vertical bars and having the adjacent tie-bar endslongitudinally split and the respective split sections bent about therespective adjacent vertical bars in opposite directions and rigidlysecured thereto, time iorming in effect aconitlnuous web, bar, and!upper and lower horizontal web bars bounding the ends of said verticalbars.

5'. A post comprising spaced" vertical supporting bars, and a spiralweb-bar bounding said vertical bars from end to end, said webbar beingdivided into individual tie-bars at its crossinigjpoints upon therespective STANLEY MAOOMBELRL
